Question

All metals are ductile.
(A) True
(B) False

Answer 1

Hint: Ductility is the property of an element to be able to be drawn into wires. It is the condition when a compressive material stretches under a tensile strain. Ductility is a mechanical property of the material. Metals like sodium, potassium are very soft and can be cut with a knife.

Complete Stepwise solution
Out of the 118 elements present in the periodic table, the majority of the elements are metal, and the rest of the elements are nonmetals and metalloids. Metals are those elements in the periodic table that are characterized by the general characteristics such as lustre, high melting and boiling points, ductility, and malleability. All the metals are generally good conductors of heat and electricity due to the presence of free electrons. But among the different elements present in the periodic table, there are some metals that are non-ductile and non-malleable, where ductility is the tendency of the metal to be drawn into wires and the malleability of the metals to be beaten into sheets.
Metals such as the alkali metals like lithium, sodium, potassium, etc. are so soft that they can be cut by a knife. There are elements like mercury and gallium that are liquid at room temperature. These elements cannot be stretched under tensile pressure into either wires or beaten into sheets. Hence these metals are not non-ductile and non-malleable.

Hence, the statement that, “All metals are ductile” is false and the correct option is B.

Notes
Metals are used in transport facilities such as to be the bodies of trains, aeroplane, ships, etc. They are used to make communication devices, utensils, electronic devices, farming devices, medical and biomedical devices, construction and bio-medical applications, etc.
